Thread milling, thread milling cutters, different structures, different materials, the thread milling method can be divided: disk-shaped thread milling thread milling, comb-shaped thread milling thread milling, CNC thread milling, whirlwind thread milling.

1．Disk-shaped cemented carbide thread milling cutter

The disk-shaped cemented carbide thread milling cutter is much like ordinary double angle cutters. It is mainly used for milling single-line and multi-line trapezoidal thread and worm.

The disk-shaped cemented carbide thread milling cutter situation shown in Figure a. Staggered cemented carbide thread milling cutter and workpiece axis angle ψ (ψ angle is equal to the thread lead angle of the workpiece). As milling spiral groove for groove milling to reduce the interference in diameter should choose a smaller number of teeth more choices, in order to maintain stable milling. To improve the milling conditions on both sides of the cutter can be ground into a staggered, in order to increase the chip space, but the need for a complete tooth profile for the test.

2．Comb-shaped cemented carbide thread milling cutter

Comb-shaped cemented carbide thread milling cutter is mainly used to processing with smaller teeth, shorter length cylindrical threaded processing of various taper thread.

Comb cemented carbide thread milling cutter constituted by a number of annular tooth pattern, the width is greater than the length of the workpiece, generally made of a shovel tooth structure for processing short triangular thread dedicated milling. Their work is shown in Figure b. Workpiece revolution cutter relative to the workpiece axis to move a lead to all milling a thread.

Thread milling and turning threaded. Turning Threading is simple contour machining, cemented carbide thread milling cutter relative to the workpiece for cutting both sports, but also for the spiral motion, the spiral surface processing is the envelope surface made by cemented carbide thread milling cutter for cutting movement rotator relative spiral movement.

3．CNC cemented carbide thread milling cutter

With the popularity of CNC machine tools, cemented carbide thread milling cutter technology, more and more applications in the machinery manufacturing. Thread milling of triaxial linkage by CNC machine tools or multi-axis, cemented carbide thread milling cutter the helical interpolation formation thread, thread cutter each for one week a circular motion in the horizontal plane, the linear movement in a vertical plane a pitch.Cemented carbide thread milling cutter have many advantages of high processing efficiency, high thread quality tool versatility, good processing safety, the user can be selected according to the own equipment, processing and object processing costs, processing batch, thread diameter and other conditions .

4．Whirlwind milling

Whirlwind milling method is a high-speed method of thread milling. Cutting external threads with the whirlwind milling head two: cut inside method whirlwind milling head and outer cutting method whirlwind milling head.

Whirlwind milling head cut inside method thread milling, cemented carbide thread milling cutter and workpiece thread contact longer, chips and longer cutting than smooth processing out of the thread surface roughness better. However, the endo Law whirlwind milling head of cutter diameter and head number of the diameter of the workpiece and the machine tool center height restrictions.

The outer cutting method Cyclones thread milling of the milling head, the contact of the cutter and workpiece threaded arc shorter, also shorter and thicker chips, thus cutting the stationary and the cut-out threaded surface roughness than that of the inner cutting method of hearing. However, the outer cutting law whirlwind milling head structure parameters are almost free from the constraints of the machine tool and workpiece size.

Whirlwind milling method of processing threads accuracy is not high, and the adjustment of the trouble, use the occasion limited, is not commonly used.
